Vertical rotation construction method of spatial special-shaped single-tower cable-stayed landscape bridge
The invention discloses a vertical rotation construction method of a spatial special-shaped single-tower cable-stayed landscape bridge, and relates to the field of bridge construction. The vertical rotation construction method of the spatial special-shaped single-tower cable-stayed landscape bridge comprises the following steps: constructing a steel-concrete embedded pier, two tower-beam combination sections mounted at the top of the steel-concrete embedded pier, two compression girders connected with the two tower-beam combination sections, and a bridge floor back cable anchoring area; a temporary support is built to fix the two steel main towers and the auxiliary towers hinged to the two steel main towers, one ends of the two steel main towers are hinged to the two tower beam combination sections, and the two sides of the two auxiliary towers are connected with the two steel main towers and the bridge deck back cable anchoring area through at least one front steel strand and at least one rear steel strand correspondingly; and the two rear steel strands are tensioned, so that the bottoms of the two steel main towers are welded and fixed after being aligned with the tops of the corresponding tower beam combination sections respectively. The vertical rotation construction method of the spatial special-shaped single-tower cable-stayed landscape bridge overcomes the defects that during bridge tower construction, splicing and welding are difficult, installation synchronism is poor, the period is long, and safety and stability are poor.
一种空间异形独塔斜拉景观桥的竖转施工方法，涉及桥梁施工领域。空间异形独塔斜拉景观桥的竖转施工方法包括以下步骤：施工钢混预埋桥墩、安装于钢混预埋桥墩顶部的两个塔梁结合段及与两个塔梁结合段连接的两条受压大梁及桥面背索锚固区；搭建临时支架固定两个钢主塔及与两个钢主塔铰接的副塔，将两个钢主塔一端与两个塔梁结合段铰接，将两个副塔的两侧分别与两个钢主塔和桥面背索锚固区通过至少一条前钢绞线和至少一条后钢绞线连接；张拉两条后钢绞线使两个钢主塔的底部分别与对应的塔梁结合段顶部对齐后焊接固定。空间异形独塔斜拉景观桥的竖转施工方法解决了桥塔施工时拼装焊接难、安装同步性差和周期长、安全稳定性差等缺点。
